3 Configuring the Switch

contains promiscuous ports that can communicate with all other ports in the private VLAN group, while a secondary (or community) VLAN contains community ports that can only communicate with other hosts within the secondary VLAN and with any of the promiscuous ports in the associated primary VLAN. Isolated VLANs, on the other hand, consist a single stand-alone VLAN that contains one promiscuous port and one or more isolated (or host) ports. In all cases, the promiscuous ports are designed to provide open access to an external network such as the Internet, while the community or isolated ports provide restricted access to local users.

Multiple primary VLANs can be configured on this switch, and multiple community VLANs can be associated with each primary VLAN. One or more isolated VLANs can also be configured. (Note that private VLANs and normal VLANs can exist simultaneously within the same switch.)

To configure primary/secondary associated groups, follow these steps:

1.Use the Private VLAN Configuration menu (page 3-175)to designate one or more community VLANs, and the primary VLAN that will channel traffic outside of the VLAN groups.

2.Use the Private VLAN Association menu (page 3-176)to map the secondary (i.e., community) VLAN(s) to the primary VLAN.

3.Use the Private VLAN Port Configuration menu (page 3-178)to set the port type to promiscuous (i.e., having access to all ports in the primary VLAN), or host (i.e., having access restricted to community VLAN members, and channeling all other traffic through promiscuous ports). Then assign any promiscuous ports to a primary VLAN and any host ports a community VLAN.

To configure an isolated VLAN, follow these steps:

1.Use the Private VLAN Configuration menu (page 3-175)to designate an isolated VLAN that will channel all traffic through a single promiscuous port.

2.Use the Private VLAN Port Configuration menu (page 3-178)to set the port type to promiscuous (i.e., the single channel to the external network), or isolated (i.e., having access only to the promiscuous port in its own VLAN). Then assign the promiscuous port and all host ports to an isolated VLAN.

Displaying Current Private VLANs

The Private VLAN Information page displays information on the private VLANs configured on the switch, including primary, community, and isolated VLANs, and their assigned interfaces.

Command Attributes

VLAN ID – ID of configured VLAN (1-4092), and VLAN type.

Primary VLAN – The VLAN with which the selected VLAN ID is associated. A primary VLAN displays its own ID, a community VLAN displays the associated primary VLAN, and an isolated VLAN displays the stand-alone VLAN.

Ports List – The list of ports (and assigned port type) in the selected private VLAN.
